The project team consisted of marine ecologists, seabed morphologists, hydrodynamical and contracting experts from consultancy agencies, contractors, applied research institutes, universities and governmental authorities. Their expertise was used during regular brainstorming sessions and an international group of experts were asked for their verdict concerning the project. Furthermore, the early involvement of stakeholders in the project team was essential for the success and the swiftness of the design-phase. The stakeholders represented all aspects of the project, from technical aspects to contracting and governance. They contributed to the project through regular meetings with the project team throughout the project development.
Some stakeholders were closely involved in the project and formally responsible for the activities at the extraction site, and for determining the exact location, shape and volume of sand in the designs. The stakeholders were:
- Contractor PUMA (Joint Venture Boskalis and Van Oord), assisting in the design, giving feedback on its workability and responsible for creating the sand bars;
- The Port of Rotterdam (PoR), responsible for allowing the pilot sand bars to be created in their sand extraction site and for the environmental monitoring programme in- and around the extraction site on the Dutch Continental Shelf;
- The Ministry of Transport, Public Works and Water Management, Directorate-General for Public Works and Water Management (Rijkswaterstaat Dienst Noordzee) which responsible for granting the sand extraction permits.
